OK guys bringing it back to the top because we drove it for one day and the same thing is happening,idles low,and when you first start it you have to have the gas pedal pushed before it will start.Maybe the computer going bad sending a bad signal?I did notice however that it has a good leak at the manifold ,could this be causing this problem?Any ideas what to do next?
Thanks David

did you clean where the plunger of the aic seats if it`s still carbon up you`ll have the sam problem, also check for vaccum leaks.
